HINGE FOR OVEN-DOORSAND THE LIKE.

Specification of Letters Patent. P t t 30, 20

Application filed August 2, 1919. Serial No. 314,940.

To all whom it may concern:

Be it known that I, EDWARD P. COLE, a citizen of the United States, residing in Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Hinges for Oven-Doors and the like, of which the following is a specification.

My invention relates to hinges more particularly adapted and designed for use in hinging the doors of ovens or ranges for cooking purposes. The object of my invention is to provide a concealed hinge structure applicable to the lower side of an oven door which shall lock the door in closed vertical position, and securely support the door in horizontal position when open; shall be capable of easy manipulation by movement of the door, and which will automatically look when the door is closed, through strong simple mechanism which will operate with ease and certainty, and which will not be liable to get out of order. With this general object in view my invention consists in the novel organization, arrangement and combination of cooperating elements of the hinge structure hereinafter described, embodying my invention in a practical and prefer-red form, the essential elements of my in vention being pointed out in the appended claims, it being understood, however, that my invention may be applied to other uses than that described, and that modification in the form and proportions of the parts may be made within the scope of the claims and without departing from the substance of my invention.

Of the drawing forming part of this specification Figure 1 is a; perspective of one hinge mechanism and associated portions of the door and oven frame lying beyond a vertical plane adjacent the hinge and viewed from a point at one side and slightly to the rear of the hinge, the door being in open position; Fig. 2 is a similar view with the door closed; Fig. 3 is a perspective from the same point of the corner of the door frame with the door removed; Fig. 4: is a side view of the hinge members on alarger scale than the preceding figures, showing in full lines the door closed and in dotted lines the position of the parts when the door is partly open; and Fig. 5 is a horizontal section on the line 5-5 of Fig. 4. The same reference characters designate the same parts in all the figures of the drawmg.

Describing now the structure illustrated in the drawings, the door casing l is secured to the oven wall in any suitable manner, the lower edge of the door opening being arranged just above the plane of the bottom wall 2 of the oven. The hinge members carried by the door consist of two flat, L-shaped arms 3, these arms in the present instance being each formed integral with a base plate which is welded to the inner wall of the hollow door, between the inner and out-er walls. One of the arms is thus secured to the lower inner face of the door, adjacent one lower corner of the door so that its free end is offset and disposed parallel to the door, and the other is similarly arranged at the opposite side, the free end of the arms extending rearwardly through slots 4 in the door casing when the door is open, and extendingdownwardly through a slot in the bottom wall 2, as hereinafter described, when the door is closed. To the outer sides of the arms 3 are secured stop lugs 5 arranged -to cooperate with the inner. face of the door casing to limit the outward and downward movement of the door, the lower edge of the door also cooperating with the outer face of the casing so that when the door is opened it will come to rest in a substantially it horizontal position with its face lying in substantially the same plane as the bottom of the oven, and serve as a shelf in transferringarticles into and out of the oven, if need be.

The bottom of the oven is formed witl opposite slots 6 in the path ofmovement of the arms 3, and cut out at the sides to avoid interference with the lugs 5, when the door is moved from open to closed position, or vice versa: and to the oven structure, in the present instance to the lower side of its hottom wall, are fixed inclined guiding and retaining members consisting of strips 7 having vertical lower portions 7, so arranged that as the door is moved from open to closed position, the lower ends of the arms 2 will slide downwardly and forwardly until they clear the inclined portions of the members 7 and drop downwardly between the vertical portions 7 and the inside face of the casing 1, the parts then assuming the position shown in Fig. 2 and the door being securely locked in closed position. The strips are formed of a somewhat .stiff resilient metal, so as to exert a certain degree of spring tension on the lower inner edges of the arms, thus holdingthe door closed under spring pressure. In opening the door it is lifted vertically until the inner or rear faces at the ends of the arms 2 clear the vertical portions 7 of the retaining members, and is then swung outwardly so that such ends of 5 when the door, standing in horizontal or i open position, is lifted bodily and then withdrawn outwardly as the lugs clear the narrower portions of the slots. It is obvious that my novel hinge mechanism may be applied to, doors of various kinds, other than oven doors, and that in so doing variations may be made in the form, proportions and particular construction of the parts without departing from the essential arrangement and organization of cooperating members constituting the hinge structure. I therefore do not limit my claims, with respect to such modifications,

to the precise details above described.

I claim:

1. In an oven having a door frame and a door, inwardly extending ofli'set arms secured to the inner lower corners of the door, said frame being formed with slots arranged to receive said arms, and guiding and retaining members secured to the oven structure and formed with outwardly and downwardly inclined faces arranged to cooperate with the corresponding end portions of said arms.

2. In an oven having a door frame and a door, inwardly extending ofi'set arms se-v cured to the inner lower corners of the door, said frame being formed with slots arranged to receive said arms, and guiding and retaining members secured to the oven structure and formed with outwardly and downwardly inclined faces and vertical faces continuous with the lower end of said inclined faces arranged to cooperate with the corre sponding end portions of said arms.

3. In an oven having a door frame and a door, inwardly extending offset arms se-v cured to the inner lower corners of the door, said frame being formed with slots arranged to receive-said arms, and guiding and re taining members secured to the oven structure and formed with outwardly and down wardly inclined faces and vertical faces continuous with the lower end of said inclined faces arranged to cooperate with the corresponding end portions of said arms, said guiding and retaining members being formed of spring metal.

4:. In an oven having a bottom wall and a door frame flush therewith and a door, inwardly extending ofi'set arms secured to the inner lower corners of the door, said door frame and the adjacent portion of said bottom wall being formed with slots arranged to receive said arms, and a forwardly and downwardly inclined guiding and retaining member secured to the underside of said bottom wall adjacent the rear end of the slot therein.

5. In an oven having a bottom wall and a door frame flush therewith and a door, inwardly extending offset arms secured to the inner lower corners of the door, said door frame and the adjacent portion of said bottom wall being formed with slots arranged to receive said arms, and aforwardly and downwardly inclined strip of resilient sheet metal having its upper end secured to the underside of said bottom wall adjacent the rear end of the slot therein.

6. In an oven having a bottom wall and a door frame flush therewith and a door, inwardly extending ofi'set arms secured to the inner lower corners of the door, said door frame and the adjacent portion of said bottom wall being formed with slots arranged to receive said arms, and a forwardly and downwardly inclined strip of resilient sheet metal having its upper end secured to the underside of said bottom wall adjacent the rear end of the slot therein, said strip. having a vertical lower portion.

7. In an oven having a door frame and a door, inwardly extending ofi'set arms secured to the inner lower corners of the door and equipped with stops, said frame being formed with slots having enlarged upper portions arranged to permit withdrawal of the arms and stops and having narrow lower portions, and portions of the frame at the sides of the narrow lower portions of said slots being arranged to cooperate with said stops, and guiding and retaining members secured to the oven structure and formed with outwardly and downwardly inclined faces arranged. to cooperate with the corresponding end portions of said arms.
